Fig. 6 is an enlarged schematic view of a portion C in fig. 5. Fig. 7 is an exploded schematic view of a skid mount of an embodiment of the present disclosure. As shown in connection with fig. 1-7, the stand of an embodiment of the present disclosure includes two support arms: first support arm 110 and second support arm 120, one of them support arm sets up the slide, realizes connecting through first connecting rod structure between two support arms to make one of them support arm slide along the slide, realize packing up the support operation, in order to save storage space.
The first support arm 110 may have a slide, such as the first slide 111, formed on one side (e.g., the outer side shown in fig. 2), and one end of the first connecting rod structure 130, which may be referred to as a first end, may be received in the first slide 111, and the first end is disposed in the slide and can slide along the slide. To seting up length of first slide 111, its one end is with seting up in first support arm 110 upper end as the limit, second support arm 120 can slide to first support arm 110 upper end along first slide 111 to two support arms are all in the state of expanding, so that the support extension, to the other end of first slide 111, with both ends length unanimous with the length of second support arm 120, when accomodating the state, second support arm 120 can laminate completely in first support arm 110 one side, so that accomodate back overall length as far as possible short. The first slide 111 may be recessed on one side of the first support arm 110.
One side surface of the second support arm 120 can be at least partially attached to the side (e.g., the outer side in fig. 2) of the first support arm 110 where the first slideway 111 is formed, and when the bracket is in the retracted state, the outer side of the first support arm 110 can be attached to a certain side surface of the second support arm 120, so that the storage space is saved. The length of the second support arm 120 may be shorter than the length of the first support arm 110 (if there is an arc, it may refer to an arc length), so that the second support arm 120 can be completely located at one side of the first support arm 110, and does not occupy an additional receiving space. Of course, the present disclosure is not limited to the second support arm 120 being shorter than the first support arm 110.
The First Linkage structure 130(First Linkage Mechanism) serves as a connecting part of the First support arm 110 and the second support arm 120, and is used for connecting the second support arm 120 and the First support arm 110, and the second support arm 120 slides along the First slide track under the driving of the First Linkage structure. In order to implement the above two functions, one end of the first link structure 130 (which may be a first end of the first link structure 130) is disposed in the first slide, and can slide along the first slide 111 under the driving of the other end of the first link structure 130 (which may be a second end of the first link structure 130), the second end of the first link structure 130 is connected to one end of the second support arm 120 in a revolute pair manner, the revolute pair connection means that the second end of the first link structure 130 and the second support arm 120 can coaxially rotate, and the first link structure is fixed in position (i.e., the second end) relative to the revolute axis of the second support arm 120, and if the second support arm 120 moves to one side under the action of an external force, the first link structure can also follow the movement.
